My ACTIVE BODY CONTROL warning is coming on/off periodically when i would stop the car switch off start again it would clear itself in the last couple of days a new warning has appeared in red text ACTIVE BODY CONTROL drive carefully !& the ride is very soft. It's off in the morning but will at least come on once a day. I have checked the fluid and notice leakage all on my left front tire with hydraulic fluid. The reservoir was down about 1/4 of a inch also the top of the reservoir is wet and some spray on the left side of the engine. My mechanic changed the filter but it has happen again. Has the pump gone bad or hose?.....all replies greatly appreciated
